    Thank God I found you. You sir are a hero. You should teach at a University instead of all the professors who pretend to teach, those who go on an on for an hour complicating things and making life harder.

      Brian Swarthout Just one question sir: at 4:15 you say that di is between C and 2f but how can that be possible? since f = (1/2)*C ==> 2f = C, right? so you're basically saying "di is between C and C." Is this right, or am I missing something? Thank you

    • @stepbystepscience
      @stepbystepscience  10 років тому +7

      Al Infinity Yes, you are right, it should say di between C and f. Sorry about that, thanks for catching my error and thanks for pointing it out to me…..that must be a copy and paste error from the convex lenses where it would say the image is between f and 2f when the object is beyond 2f. Again thank you, I will add a note to the video right now.

    Simply no other explanation is as clear as this one. I looked in my textbook, I looked at my teacher's notes, I looked at a few other videos, etc., but nothing compares to this one. Thank you so so so much for this video, you are absolutely amazing. I am on my way to watch a few more of your videos to clear up my understanding, and I also just subscribed! I will definitely recommend this channel to my friends. You have a gift for teaching; please don't stop! Thank you~

    Love this video! Just wanted to point out though that in scenario 1 (do>C), you mentioned that di is between C & 2f. However, in the diagram you have it between C & f (and also you mentioned that C=2f) so I think that was a typo!
